WIRE NAIL.

SPECIFICATION forming part of Letters Patent No. 373,499, dated November 22, 1887.

Application tiled September 27, 1886. Serial No. 214,673. (No modeli) To all whom it may concern.-

Be it known that I, WILLIAM A. SWEET, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain'ne\vand useful Improvements in \Vire Nails or Spikes, of which the follow ing is a specification, reference being had to the accompanying drawings, in which- Figure l is aside elevation, end View, of point and of head of a three-sided nail. Fig. 2 are like views of a three-sided and bluntedged nail. Fig. 3 are like views of an oval nail. Fig. 4 are like views of a three-sided railroadspike. Fig. 5 arelikc views oi'a three- Figs. 6 and 7 are like views of an oval-bodied railroadspike. Fig. 8 are details of a three-sided nail or spike with ohisel-point. Fig. 9 are details of a threesided curved-line or wedgepointed nail or spike. Fig. 10 are details of a bluntedged three-sided curved-line or wedge-pointed nail or spike.

The object of my invention is to produce a new and improved style or class of nails or spikes; and it relates, generally, to that classification commonly distinguished as wire The peculiarly strong feature of it is nails. that I produce a nail from wire, which, from its peculiar form, possesses the one particular attribute and property not possessed by any other wire nail, to my knowledge, which is most desirable and essential in a nail, in that my nail, although straight-sided,will draw in the same manner and substantially to the same extent as the common wire nail.

A is my nail or spike constructed with a body, 1, head 2, and point 3. The body of this nail or spike in its general form is triangular in. cross-section. This triangularity may be varied as to the width of the three main faces that is to say, they may all be of equal width, or two may be equal and the third one either wider or narrower than the others, or all three may be of unequal width; also, these faces may meet each other with a sharp edge; or, as shown in Fig.2, they may meet abruptly, formiug a blunt edge, thus forming a triangular nail with three main sides or faces connected together by three auxiliary faces, which may be either straight or curved. The main faces of the nail may also be either straight or curved 3 also, the meeting edges, whether sharp or blunt, may be plain and smooth or corrugated with rough or smooth indentations, or with teeth, either sharp or blunt, standing at any desired angle of presentation, and these corrugations or teeth may extend for any desired distance. The heads of the nails are also of general triangular form and out-line, corresponding generally to the triangularity of the body.

The heads of the railroad-spikes illustrated are usually made of the ordinary form, with the projecting lip to lap onto the flange of the rail. The points are in general construction adapted to present upon one, two, or three sides (or more) a triangular, or substantially triangular, face or faces to enter the wood, lying at any desired angle to the body face or faces; also, these triangular point-faces may be straightsided, or may have one straight and two of them curved, or all three may be curved; also, the general line or direction of any or all of these pointfaces may be either straight or curved as it extends back from the point or apex of the point to the body. \Vhen the lines of the point-faces are curved all in the same curve from the apex of the point back to the body, the meeting lines of these faces, forming the edges of the point, will also be curved, and when so constructed I create what I term a cur vcd-line pyramidal point, to distinguish it from a point in which the pyramidal faces are plane and their meeting edges straight. Fig. 10 illustrates this curvedline pyramidal point; also, the points may be pyramidal, as shown in Fig. 2, or wedging, as shown in Figs. 6, 9, and 10, orchiscl shaped, as shown in Fig. 8.

vIn Figs. 3, 6, and 7 I show a nail or spike constructed with a body oval or elliptical in cross-section, to which I apply my principle of triangularity in the faces of the point.

\Vhatl claim as my invention, and desire to secure by Letters Patent, is

A three-faced nail constructed with a curvedline pyramidal point, substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of September 1886.
